Section 201 protects against fairly traded imports, runs eight years maximum and must phase down. Solar expired; quartz is live.

The Section 201 solar safeguard expired in February 2026. A Section 232 action on polysilicon with minimum import prices replaces it.

Section 232 copper duties hit semi-finished products at 50% but leave refined cathode at zero. Where the line falls and what has not been triggered.

GSP expired on 31 December 2020 and has never been renewed. Why flagging entries with SPI A still matters, and what a retroactive renewal would refund.

MFN is the base duty rate and no trade remedy replaces it. How the HTSUS columns work, which four countries sit in Column 2, and the order CBP stacks duties in.

US customs value follows a strict hierarchy under 19 USC 1401a. The six methods, what must be added to the price paid, and what is excluded.

The four USMCA qualification paths, both regional value content formulas, the automotive requirements and the nine data elements a certification must carry.

Section 232 steel and aluminum duties now apply to full customs value, not metal content. Current rates, the annexes and melt-and-pour origin.

The complete landed cost build-up with current MPF and HMF figures, plus the CIF error that overstates dutiable value by 5 to 15% on every ocean entry.
